several members on the Monacoers forum have traded for a new coach with the Maxxforce engine and are very pleased with it. Their mileage is much better than the Cummins they had and it has plenty of power.

Don't know of anyone with the new Navistar product. Navistar bought Monaco (which is the parent company of Holiday Rambler) out of bankruptcy a year or two ago and most of the Holiday Rambler owners I know think they did that to expand their market for their engines. Navistar has taken the careful route by making the switch from Cummins to Maxxforce slowly, so I suspect the switch has been well planned out. It should be a good combination. Good luck.

Thanks hobo

RUN, FORREST, RUN! The new MaxxForce engines are a disaster. Proof? Ryder is not buying any more Internationals unless and until they can get them to run properly! We have ten at work (MaxxForce 11, delivered last March), and have NEVER had even nine running properly at the same time!
